Gate marked Gem pan

[Dave Canning]

Recently picked up this gem pan and cleaned it up enough to see any markings. It looks like a Waterman but the description here says raised mold marks would be found under the handles on some. This one has raised marks on the top of the handles. Would anyone recognize them? Thank you in advance

Size numbers under the handles, yes, but not molder's marks such as these appear to be. Those are typically just initials of the foundryman, and aren't significant as to manufacturer.
